    Subject[22/30] asus-laptop: add Lenovo SL hotkey support
    2.6.32-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Ike Panhc <ike.pan@canonical.com>

    commit 14f8af311e7d3e4198cbaade84a34f86505dcb37 upstream.

    Lenovo SL series laptop has a very similar DSDT with Asus laptops. We can
    easily have the extra ACPI function support with little modification in
    asus-laptop.c

    Here is the hotkey enablement for Lenovo SL series laptop.

    This patch will enable the following hotkey:
    - Volumn Up
    - Volumn Down
    - Mute
    - Screen Lock (Fn+F2)
    - Battery Status (Fn+F3)
    - WLAN switch (Fn+F5)
    - Video output switch (Fn+F7)
    - Touchpad switch (Fn+F8)
    - Screen Magnifier (Fn+Space)

    The following function of Lenovo SL laptop is still need to be enabled:
    - Hotkey: KEY_SUSPEND (Fn+F4), KEY_SLEEP (Fn+F12), Dock Eject (Fn+F9)
    - Rfkill for bluetooth and wlan
    - LenovoCare LED
    - Hwmon for fan speed
    - Fingerprint scanner
    - Active Protection System
